used to love the app, would play every day, up until this morning. I could put up with the adds after every 2/3 messages. could put up with only 4 responses a time, what I can't put up with is how money hungry the app has gotten. now, I can't even chat without 'pieces', which all cost money. It's ridiculous to practically force people to pay for your app after so long of it being alright to use for free.

I don't like the idea of the pieces update, I feel like it should go back to 799(idk if it was that many) messages and it resets at a certain time, plus the pieces decrease when you even generate a new message from the ai which I don't think is fair, I do love this app though, I don't have the money to pay for plus or ultra so yeah, but it would be nicer if it went back to how it was before the pieces update, other than that the app is good, would prefer less ads but thats all

All other rivews sum it up perfectly except for one part(I didn't read every review only like the first few) the pieces I'm not a huge fan of those I like that they allow you to use the diffrent models without the subscription but I'm not happy with how they got rid of the daily free amount of messages that auto renew as now I've either got to constantly buy new pieces or just claim daily while with the free messages I just watch a add and keep typing after a bit when I ran out.
